Learning to Make Transmission Measurements

Step 3. Measure the device

Measuring Insertion Loss

1.Reconnect your test device as in Figure 2-1 on page 2-3.

2.Reposition the measurement trace for the best view. This can be done by pressing

Scale Ref AUTO SCALE and, if necessary, adjusting the reference level, reference position, or the scale/division.

3.Press Marker and turn the front panel knob to place the marker at a frequency of interest. Read the device's insertion loss to 0.001 dB resolution as shown in Figure 2-4.

The analyzer shows the frequency of the marker location in the active entry area (upper-left corner of display). The analyzer also shows the amplitude and frequency of the marker location in the upper-right corner of the display.
